INKING ATTACHMENT FOR PRINTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 558,586, dated April21, 1896.

Application filed March 30, 1894- To all whom it may concern:

I Be it known that I, SIDNEY J HART, aeitizen of the United States,residing at Kansas City, in the county of Jackson and State oflvIissouri, have invented certain new and useful Improvements inAttachments for Printin g-Presses and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

My invention relates to an improved attachment for printing-presses,which is so arranged as to be easily adjusted to print one or morecolors at one impression.

A further object is to provide an attachment which will enable theaverage printer to produce either line or blended work at a smallexpense, and finally to make my attachment at a moderate cost.

My invention may also be said to consist in the novel construction andcombination of parts, fully described hereinafter in connec tion withthe accompanying drawings, and specifically pointed out in the claims.

In the drawings which illustrate my invention, Figure 1 represents aside elevation of the attachment connected to the upper portion of aprinting-press. Fig. 2 is a plan view of same. Fig. 3 is a perspectiveview of the ink-fount, Fig. 4 represents a plan view of one of thebevel-wheels which carries the frictional bars. Fig. 5 is a verticalsectional view of same, taken on line 5 5 of Fig. 4. Fig. 6 is avertical sectional view of one of the adjustable blocks, showing aninking-disk arranged thereon. Fig. 7 represents an inverted plan view ofthe ink-fount, showing the manner in which it is attached to itssupporting-ba-r.

In the construction of my invention I employ a rectangular frame A, therear portion of which is divided into equal spaces a by crossbar-s B,cast integral with the sides of the frame. The front portion of frame Ais left open to receive a distributing-cylinder C, journaled in bearingsc, which are secured on top of the opposite sides of the frame.

SerialNo. 505,760. (No model.)

Cylinder C is revolved by a cog-wheel Q, rigidly secured upon one end ofthe cylinder-shaft, and meshes with an intermediate geanwheel Jjournaled to one of brackets I, to which motion is communicated by amaster gear-wheel J, mounted rigidly upon shaft 9', which is also journaled in one of brackets I.

Rigidly mounted on shaft j is a ratchet wheel K, which is operated by apawl 7t, pivoted to the upper portion of a lever k. This lever isloosely fulcrumed to shaftj and car ries at its lower end afriction-roller 7a, which operates upon an irregular-shaped track k,secured on one of the rocking arms of the press.

Arranged across the frame A, and almost contacting with the frontsurface of the distributing-cylinder, is an ink-fount D, which consistsof a longitudinal trough having adjustable partitioirplates D andverticallyoperating feed-plates d, which are raised and lowered byscrews (1 secured in a cross-bar (Z their threaded lower ends engaginglugs d on the top of the feed-plates. Partitionplates D are provided attheir lower ends with studs (1, which project through a longitudinalslot (Z in the under side of the trough, and are engaged by thumb-nutscZ ,.the manipulation of which permits the adjustment of thepartition-plates as the nature of the work demands. The compartmentsthus formed in the trough by the partition-plates are iilled with thedifferent colored inks and fed to the revolving cylinder 0 beneath theraised feedplates cl.

Should the ink feed unevenly for any cause, it is smoothly pressed onthe cylinder by a contacting-roller II, journaled in bearings h, locatedon opposite sides of the rectangular frame. This roller also removes anysuperfluous ink which may accumulate upon cylinder 0.

In addition to the revolving cylinder C, I employ a stationarydistributing plate E, which is hinged to the sides of the press at ejust above the ink-fount. The front end of said plate is supported bylugs e, cast upon the sides of the press, and may be raised to gainaccess to the ink-fount.

P indicates one or more blocks, which are adapted to slide back andforth in spaces a between cross-bars I3, and are supported upon saidcross-bars by shoulders p, which are cast integral with the upper sidecorners of the block. Projecting from the under side of block P is athreaded stud p, which is engaged by a thumbnut 27 that impinges againstthe under side of the cross-bars B, when screwed up on the stud. Byunscrewing thumb-nut p block P may be moved at will. Block P also has acentral aperture 1') to receive a shank 0 depending from an inkdisk 0.Cast integral with the head of shank 0 is a roller 0, operated byfrictional bars N. The faces of these rollers are concaved to fit theconvex side of the bar which contacts therewith. These frictional barsare pivoted to the upright portion of rods in", located in slots m m andm of bevel-wheels M, the latter being j ournaled in bearin m upon thecross-bars.

Coiled around that portion of rods m which is located within slots m ares rin s m which force the rods together with the frictional barsoutwardly, so that the latter will engage the rollers o sooner than ifthey were rigidly secured to the bevel-wheels, thus insuring a longermovement to the disks at each stroke of the frictional bars.

Ink-disks O are of various sizes, according to the nature of the workrequired, and are revolved by the frictional bars N contacting withrollers 0, which are cast upon the depending shanks 0 of said disks.

Arranged upon each side of the rectangular frame are tracks F, the uppersurfaces of which are in alinement with distributingplate E. The purposeof these tracks is to relieve the ink-disk of undue pressure from theinking-rollers G, and to also provide a continuous path for rollers Gfrom distributing-plate E to said ink-disks. The operation of my machineis as follows: The feed-plates of the ink-fou nt are raiseda suitabledistance to permit the different colored inks, to feed upon thedistributing-cylinder, which is revolved by the above-describedintermediate mechanism, from whence it is carried by the inking-rollersup to the revolving ink-disks that evenly distribute the ink upon saidrollers, which are then carried back by the rocking arms over thedistributing-cylinder, the stationary distributing-plate, and down overthe type. It will thus be seen that perfect distribution of the inksupon the rollers is obtained, which will insure first-class work.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a chromatic printing-press, the combination with a suitablesupporting-frame work, an ink-supply, a distributing-cylinder, and aninking-disk, of a gear-wheel operatively connected up to operate thedistributing-cylinder and the inking-disk, a ratchet wheel mounted torotate with said gear-wheel,

alever loosely fulcrumed upon the gear-wheel shaft, and carrying aroller at one end and a pawl at the other, which engages the saidratchet, a pivoted arm, a track carried thereby and engaging the rollerof said lever, and means to operate said arm, substantially as setforth.
